dusya [7]

Answer:

p\le 14.28

Step-by-step explanation:

Total budget for school stationery = $37

She has already spent $22.72 on books and folders.

Left amount = $37 - $22.72

= $14.28

Let p represent the amount that Sally can spend on other stationery. It implies that "p" must be less than or equal to $14.28 .

Hence, the required inequality is :

p\le 14.28
